A friend of mine just bought Resident evil 5 for the PC so I've been looking where I could find a copy for the lowest price. I see cd keys for sale for like $12-13 which seems like a great deal but is it a totally legit way to buy a game. I'm asking about buying games in general like this because I see low prices for alot of game out there for just the cd key. Is it against the EULA to buy a game like this?
